How to force chan_dongle to connect on certain mobile provider

The problem is that I’m on the border of two country…and if I put the card from foreign country I have a signal but sometimes it can jump to network and start thhe roaming what is not acceptable for me.
Is there any posibilities to definate to connect on certain mobile network?

chan_dongle is not part of the core Asterisk product. I don’t think its maintainer reads this forum.

However, looking at http://wiki.e1550.mobi/doku.php?id=usage it seems to me that, if it can be done, it is done by using the dongle cmd … CLI command, probably with AT^SYSCFG… although you will need to find documentation of the specific device for details, unless the samples cover your case.

Hmm…Thx for replay…
I didn;t find there nothing worthy.

You need Huawei’s documentation.
